Be it known that I, HARVEY H. Diom- Hoor, a citizen of the United States, and a resident of Canton, county of Stark, and. State of Ohio, have invented a new and use o which the following is a specification, the principle of the invention beinherein explained and the best mode in w ich I have contemplated appling that principle, so as /to distinguish it om other inventions.

The present improvements have more articular regard to the provision of a iall bearing for taking up both radial and end,7 thrust. The object of' the invention is to provide line bearing contacts for the balls and their respective races, and improved facilities for maintaining the bearing lubricated, while, at the same time the construction is left csierple and capable of being easily assembl and taken apart. To the accomplishment of the tore/going and related ends, the invention, then, consists of fully described and particularly pointed out in the claims;

The annexed drawing and the following description set forth in detail certain mech anism embodying the invention, such disclosed means constituting, however but one oi various mechanical forms in which the principle of the invention may be used.

In said annexed drawing A Figure 1 is a diametral section of a bearin employing. my present im rovements; an Fi 2 is a similar view o a modified form o construction of thesame.

As illustrated in Fig. 1, the bearing comprises the usual inner and outer tubular members 1 and 2, the former designed to fit on the shaft or spindle, and the latter in the box or casing of the relatively rotatin part. The races for the balls are prov1 ed in part by means of an integral ange 3 on the one lend of such outer member, such {iange being formed with a polygonal groove 4 that constitutes one side ofthe race-way for one set of balls. Such groove may be but an larl related side-walls against which t e ba s bear on a line contact. Two axially llpaced rings 5 and 6 interposed in the ann ar space between thetw'o mbers, one such ring having similar ves 7 on both its iaces,'and vtheothera single .f cove -8 on its inner face, ccmpiete the races or the two sets of balls t and 10 vihe inediate and the' Iwhich the balls travel,

ring 6 is tightly tted onto lar' member, threaded into the outer member and securely locked in place'by means oia lookin ring 11, as will be readily understood, t'ereby constituting wardly directed ange ormember 2 of said ring 7' a detachable, 1n-

y the inner. tubu- 4 while the last-named ring 7 is In the modified construction illustrated Fig. 2 instead of the outer member 12 being formed with4 an integral iange, 4as in the first-described nstruction, such integral flange 14 is formed on the inner member 13,

press-fitted or otherwise non-rotatably secured to the outer member, the'remalning ring or vsecond end-flange 16 being threaded onto the inner tubular member, and there intermediate ring 15 is accordingly locked by means of a lock ring 1'?, just as ways,

passages 22 being sired, toinsure thorou lubricant.-

. From the foregoing description it will be observed that my improved ball bearing is v ls 19; in addition, the intermediate ring 15 is pro-l a Aconduit Qlior lubricant in the" additional transverse communicating f formed in the ring if de h distribution of such l not only self-contained, but that the balls v are so inclosed as to permit of the retention of lubricant therein independently .of whether the bearing as an entirety is inclosed. This insures the placing of the lubricant just where needed, without having to have the entire boxing lled with grease, as is necessary with current types of ball bearings. Furthermore, by reason of the unique polygonal grooves, or recesses, in

they are adapted to resist both radial and end thrust, and yet it lwill be observed, have only a double line contact with each side of the race, instead.

of traveling in grooves of corresponding curvature and cross-section, which means a very considerable increase in the amount of friction developed. Finally, the parts of my improved bearing are capable of being readily assembled and taken apart, since it will suee to simply loosen the lock-ring,-
